Playstation 4 has been ripped apart to reveal whats inside the box. The PS4 dissection has revealed some interesting facts.
It was rumored for some time that the PS4 would have a secondary processor, well its not a rumor anymore. There is indeed a secondary processor, it's an SCEI CXD90025G lower power ARM solution. The actual use of the secondary processor isnt exactly known right now, although it is speculated that it is used for background downloading , or DRM handling amongst other things.

The extra 2Gb thatâ€™s really 256MB, 2 Gigabit rather than 2 Gigabyte .If you think about it, that 256MB for the background processes is the same amount of RAM dedicated to the GPU on the PS3!
